Cant really remember the size,so cant help you.But...make sure the pump seal is correctly seated.Mine wasn't and the seal corroded in no time and had to be replaced.Tell tale sign is the strong smell of v power whilst driving

matty was just going to post the same thread up. i have a type ra (96). and i put a walbro fuel pump in. took my old one out and looks much more bigger then the walbro one. my question is which one is the better one. and another thing is ive put a fuel pressure reg on the car too. when i hit about 6 rpm its starts to miss ... is it because its running to rich or is it the fuel pump ?
